Kelam Career Institute Interview Questions and Answers

Coordinates in total station can be found by measuring distances and angles from known points.

• Set up the total station at a known point with known coordinates

• Measure the distance and angle to the point you want to find the coordinates for

• Repeat the process from multiple known points for better accuracy

• Use the measured distances and angles to calculate the coordinates of the point

To calculate RL, add the instrument height to the staff reading. For level traverse in auto level, set up the instrument at each point and take readings.

• To calculate RL, add the instrument height to the staff reading at each point.

• For level traverse in auto level, set up the instrument at each point along the traverse line.

• Take readings at each point to determine the height differences between points.

• Use the readings to calculate the RL of each point along the traverse line.

OGL stands for Optical Ground Level. It is used in auto levels for setting up the instrument at a known height above the ground.

• OGL is the height of the instrument above the ground level.

• To set OGL in an auto level, the instrument is placed on a tripod and the height is adjusted using the leveling screws until the crosshairs are at the desired height above the ground.

• OGL is important for accurate measurements in surveying and construction projects.

To layout in any plot by Total station, set up the Total station at a known point, input coordinates, measure distances and angles, and mark points.

• Set up the Total station at a known point with good visibility of the entire plot.

• Input the coordinates of the known point into the Total station.

• Measure distances and angles to locate other points in the plot accurately.

• Mark the points using stakes or paint for future reference.

• Repeat the process for all desired points in the plo...read more

Traverse is a surveying technique used to determine the relative positions of points on the earth's surface.

• Start at a known point and measure the distance and direction to the next point

• Continue this process until all points have been measured

• Use trigonometry to calculate the coordinates of each point based on the measurements

• Check for closure by comparing the calculated coordinates to the known starting point
